The invention relates to the field of suspension cables of bridge parts, in particular to an inhaul cable with sealing structure rain covers and a manufacturing method thereof. The inhaul cable with the sealing structure rain covers comprises a cable strand body (1). The inhaul cable with the sealing structure rain covers is characterized by further comprising a cable duct (2), shock absorbers (3), a sealant (4 ), the rain covers (5), a sealing ring (6), an end cover (7) and air bags (8), wherein the cable strand body (1) is sleeved with the cable duct (2), and the two shock absorbers (3) arearranged on the cable strand body (1) in a hooped mode; the two ends of the cable duct (2) are correspondingly sleeved with the rain covers (5); the air bags (8) are arranged on the inner side of theend cover (7) and between the outer side of the cable strand body (1) and the inner sides of the rain cover (5). The manufacturing method of the inhaul cable with sealing structure rain covers is characterized by comprising the following steps of in sequence (1) installing the shock absorbers; (2) arranging the rain covers; (3) arranging the air bags and (4) closing. The inhaul cable with sealingstructure rain covers is simple in structure, convenient to install, good in sealing performance and long in durability.
